Sigma 85mm f/1.4 DG HSM Art Lens for Sigma SA (321956)

Just a quick FYI: This lens has a T-STOP of 1.7 (For any cinematographers or photographers that care). So the light making it out the back is pretty good. Not perfect at about a half stop of exposure, but it's by far not that bad.At first I thought, it's crazy, why would I spend $1200 on a lens to just take pictures of my cat. But then I got the lens and I've gotta say, this is by far the BEST cat picture taking lens available. I will say, though, I wish it had some weatherproofing or should I say, drool resisting at the very least!I started taking pictures of my cat though and boy, was I hooked! My cat never looked so good (And he knew it!)!On a more serious note, this lens is a beast. I've had no issues using it whatsoever on my D500. Once I dialed in the focus on the lens (Which literally took me about 10 - 15 minutes), it's been razor sharp (You can use this with the Sigma USB Dock, not included, but just so you know). Focusing has been fast and precise. Bokeh is glorious and creamy. The lens isn't that heavy (But then again I'm used to hand holding 7lb lenses). The build quality is fantastic, and the giant focusing ring is a pleasure to use for photos and videos. The lens hood feels great, and the case the lens comes with is also pretty adequate. The only issue I have with the lens is the lens cap, but it's really nothing to complain about I just hate how you put it on and take it off. It's a great lens and if I had the choice of buying this lens or something else, I'd definitely pick this one up again.I will say that compared to this and my 150-600 Sport lens from Sigma. I definitely feel like I have to baby this lens considerably more. This definitely feels like a lens that's aimed for studio use or only to be taken out on nice days.Sigma has stated that this lens (Among many other ART lenses) is NOT meant to be out in harsh weather, and it is definitely not meant to be outdoors during pouring rain for an extended period of time. If you are going to use this lens outdoors unprotected and in harsh weather... Be warned that the lens might not be able to take it.Update from 6/2/17:After using this lens for the past few months, I gotta say I'm still in love and it's really good value for what you get.I want to take a minute though and go over some things that some people have had issues with.So, first things first. This is still a relatively cheap lens. Granted, it's not $100, $500... But this isn't a 200 f2. You're not spending over $5,000 on this lens. Even some 70 - 200 2.8's from Nikon and Canon need to be calibrated and they're around the $2000 mark. They aren't always perfect either. There are bound to be some of this lens that aren't perfect, that's just how manufacturing goes. They don't have the time and resources to make sure every single one of these lenses that goes out are absolutely perfect, and nor can they. Whatever body they might use and test could be completely different from what you're using and might not make ANY difference.Using the Sigma Optimization Pro software is literally one of the most useful things and I would say almost required if you have a Sigma lens. You need to get the Sigma USB dock (I got mine for free when I got my 150 - 600 Sport lens but I believe it's $60) Sigma makes it extremely easy for you to fine tune the focus on your lens.I've attached a picture showing my lens, and what my adjustments are (Obviously, this is only for this one specific lens). But it is SO easy to fix back and front focusing, all you need to do is spend 10 - 15 minutes, and that's it. It'll be perfect.There are actual cases though of lenses that ARE too far gone to be fixed. If you go the ENTIRE range from -20 and +20 and nothing helps... Then in that case, I would send the lens back. However, some people are saying they sent back multiple lenses more than likely isn't a lens problem, it's a problem with that person and not knowing how to fix this on their own. They likely expect it to just be perfect straight out of the box, which isn't how most lenses work (At least, under the $3000 range).If you have a problem with this lens and you're not fine tuning the focus (Assuming of course that you have a body that is able, if you don't then you probably shouldn't be shooting with this lens.), there isn't a lens problem there... There's a you problem.The only other thing I want to bring up is that this lens (It should be obvious anyway) does NOT have any sort of VR/IS of any sort. I know people who got this lens and for some reason was under the impression it had some sort of image stabilization. It does not. If you tend to shoot at slow shutter speeds and rely on VR/IS to make your photos sharp... You'll only be disappointed here because that doesn't exist so all you're going to get are blurry photos.Also note that this is similar to other Sigma lenses, which means it does tend to hunt quite a bit. That's just how a lot of them are, it's something you should be aware of. There's plenty of videos and reviews online that talk about this. Even in well lit, optimal condition this lens will tend to hunt more than first party lenses.

I purchased this lens about 3-4 months ago and have done extensive work with it since. I have been a huge fan of Sigma and the Art series lives up to the hype. The image quality, sharpness, bokeh, color, and auto-focus is stunning. It is heavy and large, but well balanced and comfortable. I am used to hand holding much larger lenses, so I was not bothered at all by the size and girth of the lens. The low light performance is very impressive with minimal hunting and seeking. The barrel distortion is nearly non-existent. There are issues with blue CA in some images, especially in brighter scenes using max aperture, but it does go away if you stop down. This has only been an issue with some product photography, specifically with bright metallic objects with edges (Silver coins and jewelry). The lack of OS is disappointing at times, but rarely becomes an issue since I use a tripod for most portraiture. Some may find the weight a challenge, especially with a mirror-less camera. However, the balance is great with the 80D with vertical grip or comparable setup. I strongly recommend this lens for serious portrait and wedding photographers. It has some great uses in the field for landscape photography and is very limited for product photography due to its minimal focus distance. Considering it is 1/2 the price of the Canon f/.4 USM IS lens with higher resolving power and sharpness, it may well be worth not having OS. If you absolutely need OS because you are doing a lot of low light work, go with the Canon, otherwise, the Sigma is a near perfect lens. Check out Dxomark for its scores.

I'm a senior portrait photographer and have used my Nikon 50mm 1.4 for years. I've eyed this Sigma 85 Art since it came out but could never justify the purchase since my 50 mm was on my camera almost 90% of the time and my clients loved their images. With Covid-19 I had to rethink how I was shooting and I didn't want to be right up in my clients faces so I finally bit the bullet and bought this lens and OMG it has blown me away! I also have a Sigma 35mm Art lens so I knew it would be good but I had no idea how much better this lens would be even that my previous Art. The bokeh is creamy and this thing is tack sharp. I noticed right out of the box it was front focusing just a bit but with a slight correction with my Sigma dock it nailed focus on about 90% of my shots from this session. Every image looked great right out of camera and because of that my editing time was cut down significantly! I'm normally correcting for all sorts of crap but not this time. It also gave me the added distance I was looking for to be safe for me and my clients.One note - this lens is a BEAST! It's heavier than any other lens I own by a lot, including my 90mm macro lens. But I will take the added weight if it means I get images like this every time!

I am NOT a professional! I am a hobbiest who is learning and I've heard great things about the 85mm! Read reviews. Checked out MANY different options and I decided to go with the Sigma since it seemed to be the best lens for quality and price! I do not regret it! These were just some practice photos I took, the day I recieved it, just to get the feel for it. I can not believe how amazing these photos are. The colors are vibrant, the bokeh is great, the photos are very sharp, and the focus is on point! I am very excited to try this lense on some actual clients and not just animals and objects around the farm.If you are new to photography and are truly wanting to push more for a career, I would say this lense is a GREAT start for you. My photography friends use it as well and absolutely love it, which is why this lense was recommended to me. And now I am recommending it to anyone who sees this. You will not be sorry for the money you spent.
